摘　　要：本文提出了利用薄层树脂相通过光度法测定痕量铁的新方法。铁离子与硫氰酸钾形成红色络合物，将其富集在Ｈ＋型００１×７阳离子交换树脂上，通过制作成薄层直接测定。本法装皿容易，选择性好，用于天然水和化学试剂中痕量铁的测定，结果满意。A new analytical method with the thin-layer resin -phase spectrophotometryfor determination of traces iron was developed. A colored complexes was obtainedfrom Fe(Ⅲ ) ion and KSCN and then enriched on cationic exchange resin (732) ti.The concentration of trace iron was direct determined by the thin layer of canonexchange resin. The method possessed a better sensitive, selective and rapid characteristics. The method has been used to determine iron in natural water andreagents with satisfactory results.
